文摘The techniques of cutting propagation of Potentilla fruticosa was studied.The tender stem cuttings and the woody stem cuttings were treated by different concentrations of BBA(0 mg·kg-1,10 mg·kg-1,50 mg·kg-1,100 mg·kg-1,200 mg·kg-1,500 mg·kg-1).The results indicated that the rooting percentage of tender stem cuttings at the concentration of 10 mg ·kg-1BBA was the highest(88.3%),and that of woody stem cuttings treated by the concentration of 50 mg·kg-1BBA was the highest(66.67%).It also indicated that the rooting percentages of the tender stem cuttings were better than those of the woody stem cuttings with same treatment.
